On April Foolsday in 1976 Steve Jobs, Steve Wozniak, and Ron Wayne signed the founding contract for Apple Computer. Eleven days later, Ron Wayne decided to sell his 10% of the company for $800, which is now worth $3.9 billion. The founding contract that made history was originally expected to sell for $150,000, but today sold for a cool $1.6 million to Eduardo Cisneros, chief executive officer of Cisneros Corp, at a Sotheby’s auction in New York, reportsBloomberg. The Cisneros family is the second wealthiest in South America according to a 2006 Forbes listing.

The story goes that apparently the consigner bought the legal papers back in the mid-1990s “from a manuscript dealer” who is thought to had acquired them from Wayne. We’ve posted the bidding after the break.

Update: we’ve confirmed the documents have sold for $1,594,500, but the $1.3 million that Fortune reported doesn’t include the buyers tax the auction house tags on. Thanks Dewitt!
